I'm not sure either.  This was already in Policy prior to this round of
changes, of course, but maybe since we're revising this section anyway,
this is the time to remove it.  To remove it, I'd drop the should and
turn it into something that we permit, like:

          <p>
            Configuration files for window managers and display managers
            may be placed in a subdirectory of <file>/etc/X11/</file>
            corresponding to the package name.  Other X Window System
            applications should use the <file>/etc/</file> directory for
            configuration files unless otherwise mandated by policy
            (such as for <ref id="appdefaults">).
          </p>

However, use of /etc/X11 for window manager configuration is fairly
widespread already, so I'm not sure if we'd be losing something by
weakening this.

Copying debian-x for an additional opinion.

I may go ahead and commit this change with sufficient seconds despite
this discussion since the above isn't a new requirement, just one that
moved around due to the reorganization of the section.  But it's always
nice to sort out a whole section when we revise.
